Definitions

  • the present invention belongs to the technical field of chemical industry, and particularly relates to a catalyst for preparing propylene glycol phenyl ether and a method for synthesizing propylene glycol phenyl ether.
  • Propylene glycol phenyl ether is a colorless transparent liquid with mild odor, and is non-toxic and environmentally friendly. Propylene glycol phenyl ether is a typical high-efficiency film-forming auxiliary. After adding into a latex system, propylene glycol phenyl ether can be redistributed in the aqueous phase and the polymerization phase, with an extremely small distribution coefficient in both phases, thereby ensuring excellent film-forming performance, good plasticizing-effect and the appropriate evaporation rate balance.
  • Propylene glycol phenyl ether has a strong solubility in most latexes and has a poor water-solubility, ensuring complete absorption by the latex particles and thereby allowing the latex paint to have the best color uniformity, coalescence performance, and excellent storage stability.
  • Propylene glycol phenyl ether can also be used as an excellent high-boiling organic solvent and an modification auxiliary to replace solvents that have higher toxicity and heavier odor, such as isophorone, cyclohexanone, benzyl alcohol or ethylene glycol phenyl ether.
  • Propylene glycol phenyl ether is widely used in areas such as automobile and automobile paint repair, electrophoretic paint, industrial baking enamel and ship, container and wood coating, due to its non-toxicity, good miscibility, moderate volatilization rate, excellent coalescence and coupling ability, and low surface tension.
  • propylene glycol phenyl ether is generally produced with two synthetic processes.
  • One process is to produce propylene glycol phenyl ether by using chloropropanol and phenol as reaction substrates, but a large amount of waste is easily produced when chloropropanol is used as a substrate.
  • the second process for synthesizing propylene glycol phenyl ether is to carry out ring-opening polymerization of phenol and propylene oxide (PO) in the presence of a basic catalyst such as sodium hydroxide or potassium hydroxide.
  • a basic catalyst such as sodium hydroxide or potassium hydroxide.
  • the second process is an industrial production method mainly used at present, but the propylene glycol phenyl ether product synthesized by using the above catalyst contains metal ions such as potassium and sodium ions, and thus cannot be directly applied to industrial fields where metal ions are strictly restricted. Subsequent processing is required to remove metal ions, resulted in complexity in the operation of the entire process as well as increased production cost of propylene glycol phenyl ether.
  • the present invention is designed to overcome the defects that the propylene glycol phenyl ether synthesized by using the catalyst in the prior art contains metal ions and thus cannot be directly applied to industrial fields where metal ions are strictly restricted, and that subsequent processing is required to remove metal ions, resulted in complexity in the operation of the entire process as well as increased production cost of propylene glycol phenyl ether.
  • the present invention provides a catalyst suitable for use in preparing propylene glycol phenyl ether which is free of metal ions and does not need subsequent processing to remove metal ions.
  • the present invention provides use of a quaternary phosphonium salt compound as a catalyst for preparing propylene glycol phenyl ether.
  • the quaternary phosphonium salt compound is selected from the group consisting of methyltriphenylphosphonium bromide, ethyltriphenylphosphonium bromide, propyltriphenylphosphonium bromide, butyltriphenylphosphonium bromide, and any combination thereof.
  • each constituent in the combination is present in an amount of 1 to 99 parts by molar.
  • the present invention provides a method for synthesizing propylene glycol phenyl ether, comprising the steps of: preparing a mixture by mixing phenol with the above quaternary phosphonium salt compound, and carrying out a polymerization reaction of the phenol and a propylene oxide by adding the propylene oxide into the mixture under oxygen-free conditions, producing a propylene glycol phenyl ether.
  • a molar ratio of the phenol to the propylene oxide is 1: (1-1.15).
  • the quaternary phosphonium salt compound is added in an amount of from 0.05% to 0.3% by mass based on a total mass of the phenol and the propylene oxide.
  • the polymerization reaction is carried out at a temperature of 100°C to 160°C and a pressure of less than or equal to 1.0 MPa.
  • the above method for synthesizing propylene glycol phenyl ether further comprises a step of raising the temperature to 80°C and controlling the temperature to be 80°C to 160°C and the pressure to be less than or equal to 1.0MPa prior to adding the propylene oxide, and then adding the propylene oxide
  • the above method for synthesizing propylene glycol phenyl ether further comprises the steps of: controlling the temperature at 100°C to 160°C and aging for 2h to 10h after adding the propylene oxide to obtain the propylene glycol phenyl ether; and then controlling the temperature at 100°C to 130°C and performing vacuum pumping at the temperature of 100°C to 130°C.
  • the propylene glycol phenyl ether products prepared in Embodiments 1-7 were analyzed with a flame photometer to detect the content of metal ions, and were analyzed with an AquaTint automatic colorimeter (purchased from Lovibond, Germany) to detect the chromaticity. The results are shown in Table 1: Table 1 Test results of propylene glycol phenyl ether products prepared by the method described in Embodiments 1-7.
  • Embodiment 1 10 0 0 Embodiment 2 5 0 0 Embodiment 3 10 0 0 Embodiment 4 10 0 0 Embodiment 5 5 0 0 Embodiment 6 15 0 0 Embodiment 7 10 0 0
  • the propylene glycol phenyl ether products prepared by using a quaternary phosphonium salt as a catalyst contains no potassium and sodium ions, and does not require subsequent operations or rectification separation to remove metal ions, so the produced propylene glycol phenyl ether products can be directly applied to industrial areas where metal ion concentration is severely restricted. Meanwhile, the method for synthesizing propylene glycol phenyl ether provided above simplifies the operation process of the whole synthesis process, reduces the synthesis cost of the propylene glycol phenyl ether, and the synthesized propylene glycol phenyl ether products have wide industrial application range.
